Before detailed drawings or technical plans are produced, there is a critical early stage known as sketch design. At this point, an architect like ourselves prepares initial drawings to explore ideas, test layouts and establish the direction of a project.
This mini guide explains what sketch design involves, how it sits within the wider architectural process, and why it matters for homeowners planning a new build, extension or refurbishment.
What is sketch design in architecture?
Sketch design is an early stage in architectural planning. It involves preparing initial drawings that explore layout, scale, proportion and the spatial arrangement of a building before any technical or construction information is produced.
These are not construction plans or drawings for contractors. They are exploratory tools used to test ideas and set a clear direction before time and resources are committed to detailed design.
At this stage, your architect will focus on:
- Making sense of your brief and project goals
- Exploring alternative layouts and floor plan options
- Understanding how the building relates to its site
- Assessing the overall form, massing and proportions
- Considering planning constraints
Addressing these points early keeps your options open and avoids costly changes later in the project.
How sketch design fits into your architectural project
Sketch design bridges the gap between your initial brief and a developed design proposal. It allows key decisions about layout, access and appearance to be considered before technical coordination with structural engineers or other consultants begins.
During this phase, your architect may:
- Present and compare alternative layout options
- Review circulation, access and how people move through the building
- Assess natural light, solar orientation and ventilation
- Consider the general organisation and flow of spaces
For you as a client, the sketch design stage gives you clarity early on. Revisions are straightforward at this point, far less disruptive and costly than changes made once planning drawings or building regulation plans are underway.
From sketch design to planning drawings and building regulations
Once the sketch design is agreed, the project moves into a more detailed phase. This typically involves preparing planning permission drawings and, subsequently, building regulation plans. Each stage builds on the last, refining the design and adding the technical information required.
The design typically progresses through the following stages:
Rough sketches
Early freehand or digital drawings used to test ideas and establish the general direction of the scheme.
Concept drawings
More resolved drawings that clarify scale, layout and general appearance. These may include early floor plans, elevations and section drawings for client review.
Developed designs
Detailed drawings that form the basis of technical information, structural coordination and construction documentation.
Each stage increases in detail and precision. At the later stages, proposals must comply with building regulations and relevant building standards, with applications submitted to the Local Authority or a building control body as part of the statutory approval process.
Why sketch design saves time and money on your project
Sketch design is one of the most valuable stages in the architectural process. It establishes a clear direction, helps avoid costly mistakes and gives you – the client – real input before significant resources are committed.
Taking time at this stage supports better decision-making and smoother progress through later phases. Whether the project involves new builds, home extensions or refurbishment, a considered sketch design can contribute to a coordinated and predictable outcome.

Frequently asked questions about sketch design
How long does the sketch design stage take?
This varies depending on the size and complexity of the project. For a straightforward house extension, a sketch design can be completed within two to four weeks. Larger or more complex schemes may take longer, particularly if significant revisions are required.
Do I need sketch designs for planning permission?
Sketch designs are not submitted directly for planning permission; they come before that stage. However, they are used to develop and agree the design before preparing the formal planning permission drawings that are submitted to the Local Planning Authority. Having a well-considered sketch design in place makes the planning drawings stage more straightforward.
How much does sketch design cost compared to the whole project?
Sketch design typically represents a relatively small proportion of the overall architectural fee – but it is one of the most cost-effective investments you can make. Resolving layout and design issues at this stage is significantly cheaper than making changes once planning drawings or construction documentation are underway.
